SIMULATION GAS-DYNAMIC PROCESSES OCCURRING IN THE HELICOPTER ENGINE MI-8MTV

Abstract

Numerical modeling of gas-dynamic processes occurring in the turbo-engine of the Mi-8MTV helicopter is carried out in the work. Numerical solutions of the Navier-Stokes equation describing turbulent gas-dynamic flows in sections of the engine cavity are applied. The space-time distribution of the flow velocity components in the engine cross sections and the time distribution of the kinetic energy are obtained. The obtained indicators are informative criteria for diagnosing the state of an aircraft engine. Earlier obtained evidence of sound generation by subsonic flow around various depressions on the blades and in the fuselage of the helicopter is confirmed.
